I'm sure I can speak for one and all when I say that a common fantasy is one of tribal sex.
You know, a bit of hanky panky with some ladies from a hunter gatherer tribe of the Amazonian rainforests or doggy doggy with a bit of hot totty from a remote mountain top tribe of New Guinea.
My own personal perversion fantasy would be that of a day of passion on the sun baked sand of the Kalahari with the ladies of the Himba tribe (see below).
How about yourself ?
